CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation of U.S. patent applicationSer. No. 13/479,818 entitled Fabrication and Tracking, filed on May 24,2012, which claims priority to U.S. Provisional Patent Application61/489,753 entitled Fabrication and Tracking, filed on May 25, 2011, thecontents of which are hereby incorporated by reference herein, in theirentirety.

FIELD

The present description relates generally to devices and processes forstreamlining the construction process. More particularly, thisdescription relates to automating an otherwise fragmented process ofdesign, fabrication, delivery, and installation for a constructionproject. Still more particularly, this application relates to devicesand processes for interpreting a design for a project, controlling andmonitoring forming and/or fabrication of the components or parts of thedesign, monitoring and/or tracking the delivery and installation of theparts in the project, and comparing the installation to the design.

BACKGROUND

The construction of a building, for example, involves several differentparties who are all involved in a coordinated effort to construct thebuilding. On the front end or design portion of a project, the partiesinvolved may include an architect, a structural engineer, a mechanicalengineer, an electrical engineer, and often an information technologyconsultant or engineer. In a design-build project, a constructionmanager and/or one or more contractors may also be involved in the frontend or design portion of the project. During construction of theproject, a general contractor or construction manager may manage theproject and several sub-contractors having particular expertise mayconstruct particular aspects of the building. For example, a structuralsteel contractor may erect the steel structure, a mechanical or heating,ventilation, and air conditioning contractor may install theserespective systems, and an electrical contractor may install theelectrical components of a building.

The several parties involved during the construction of the project mayread, study, or otherwise interpret the design prepared on the front endof a project. This generally includes reading plans and specificationsand often preparing shop drawings for fabrication of the party'srespective portions of the project. The shop drawings may then bereviewed by the designing entity and, once approved, used by afabrication facility to fabricate the several components of the party'sportion of the project. The several components may then be shipped tothe project site and installed.

As the several parties involved during construction coordinate theirefforts, a contractor or other construction manager often monitors theirwork for purposes of coordinating and scheduling the several aspects ofthe project. In addition, the work may be monitored for purposes ofprogress payments. That is, contractors are often paid based on theirpercent completion. It is common for percent completion to be relativelycursorily developed. That is, the general contractor may ask theelectrical contractor how far they are and the electrical contractor mayroughly estimate that they are 30% complete, for example. The generalcontractor may then make a payment to the electrical contractor in anamount approximately equal to 30% of the electrical contract amount.

DETAILED DESCRIPTION

The present description relates to mining data from a model and usingthe data to construct several parts reflected by the model. The presentdescription further relates to identification of the several parts,tracking of the delivery of the several parts, and tracking of theinstallation of the several parts. Still further, the descriptionincludes discussion of comparing the installed parts to the model atleast for determining a percent complete.

In one embodiment, a system is provided for mining data from a BuildingInformation Model (BIM). The system may be adapted particularly for theelectrical contracting industry and may mine data from the BIM modelrelating to the electrical systems of a building, for example. Thesystem may thus interpret the BIM model and develop shop detail-levelinstructions for fabrication of the parts of the electrical system. Thesystem may include a control system and several devices. For example,the system may include devices for picking the raw materials for theparts and identifying the parts as part of an assembly. The system mayfurther include fabrication machines such as benders, cutters, or otherdevices used for preparing a part for installation. Bundling orotherwise grouping the several parts may also be conducted by thesystem.

Once fabricated or otherwise ready for installation, the parts may beshipped to a project site and installed. Throughout these laterprocesses, the system may be equipped with a tracking module fortracking the status of the several parts. The tracking information maybe transmitted or sent back to the system for comparison to the BIMmodel. The system may compare the installed parts to the BIM model anddetermine an accurate percent completion.

Referring now to FIG. 1, a diagram is shown including several devicesand systems 100 for implementing the method. The diagram includes adepiction of a design facility 102, a pre-assembly facility 108, and aproject site 142. In the design facility 102, for example, engineers,designers, and/or contractors may design a project and preparespecifications. In the pre-assembly facility 108, a contractor, forexample, may prepare particular components for portions of the design.The components may be delivered to project site where they may beinstalled. Each of these locations 102, 108 may have systems and devicesfor performing a portion of the method to be described and systems anddevices may be fully or partially coordinated.

The engineering facility 102 may include design related devices andsystems. In one embodiment, the engineering facility 102 may include amodeling system 201 where the designing entity may input data relatingto a particular design aspect of a to-be-constructed building or otherfacility. For example, a structural engineer may input column locationsand sizes and beam locations and sizes. An electrical engineer and/orcontractor, at the same or separate design facility 102, may enterconduit sizes and locations. The model 201 may be used by the severaldesigning entities to compare each of their respective designs andhighlight conflicting areas where, for example, portions of theelectrical design cross-over or run into portions of the structuraldesign. Other conflicts that raise concerns regarding theconstructability of the layouts may also be addressed using the model201. As such the designing entities may include most or even all of theelements of their design in the model 201 to be sure no particularelement conflicts with any element or elements of any other designingentities design. In some embodiments, the model used by the severaldesigning entities may be a building information modeling system (BIM).Some examples of software used for this modeling include REVIT, AutoCADMEP, CAD Duct, CAD Pipe, Navisworks manage, and others. Still othersoftware packages for modeling a facility may also be used.

The pre-assembly facility 108 may be configured to interpret thedesigning entity's design and provide particular components to implementthe design. In some embodiments, as will be described in more detailbelow, the pre-assembly facility 108 may access the model 201 preparedby the designing entity or entities and mine data from the model 201 todevelop the components for constructing a particular portion of thedesign. Accordingly, the pre-assembly facility 108 may include acomputing device 110 connected to a network 106 for accessing the BIMmodel 201 of the designing entity. The network 106 may be a wide areanetwork such as the Internet, for example, or a local area network maybe provided. The computing device 110 may include one or more inputs,one or more outputs, a computer readable storage medium, and aprocessor. The computing device 110 may also include a user interfaceincluding a computer screen, mouse, keyboard, and the like, eachconnected to an input for providing user instructions to the processor.The computer readable storage medium may include computer implementedinstructions and/or software including steps or operations or sets ofsteps or operations for performing the methods described herein.

In conjunction with the performance of the methods described herein, thecomputing device may have a plurality of modules stored therein forinteracting with other devices of the system and coordinating and/orcontrolling portions of the method. For example, an interpretationmodule may include computer implemented instructions for interpretingthe design model 201 and developing a list, table, or other index of thecomponents for a project including details for the fabrication of thecomponents. Another example may include a selection module includingcomputer implemented instructions for controlling the devices used toselect the raw materials. Still other examples of modules may include anidentification module, a sorting module, a conveyor module, a cuttingmodule, a bending module, a bin/yard module, a delivery module, a sitemodule, an installation module, and a comparison module.

Each of the above-listed modules or other modules may include software,hardware, or a combination of software or hardware configured withcomputer implemented instructions for performing the respectiveoperations of the method to be described below. The modules may bestored on the computer readable storage medium of the computing device110 or some portions or the whole of the module may be stored on therespective device performing the respective portion of the method. Inaddition, combinations of all or a portion of the several modules may beused to perform in one or more of the operations described in themethod.

An initial step in providing particular components of the design mayinclude selecting suitable raw materials. In the case of electricalconduit, this may include selecting a suitable pipe size and pipe type,for example. Accordingly, the pre-assembly facility 108 may include araw material picking device 114. In the case of electrical conduit thedevice may be a pipe selector 114 and the device may be adapted toselect a pipe from a rack 112 having a variety of pipe types and sizesstored thereon. In some embodiments, as shown, the pipe selector 114 mayhave one or more graspers for grasping and handling the pipe. The pipeselector 114 may include an arm with the graspers positioned thereon andthe arm may be pivotable relative to a support and/or the support may berotatable. Once selected, the pipe selector 114 may remove a pipe from arack, for example, and send the pipe down a conveyor 118 for furtherprocessing and/or fabrication. In other embodiments, the raw materialpicking device 114 may include a series of gates arranged on the piperack 112 where opening of a selected gate may allow a selected pipe toroll off of the pipe rack 112, for example. Other material handlingdevices for picking raw materials may also be provided.

The pre-assembly facility 108 may include a conveyor 118 for moving thecomponents of a project through the facility. The conveyor 118 mayinclude one or a series of conveyors 118 arranged to deliver thecomponents to each of the stations of the pre-assembly process. Theconveyor 118 may be a belt-type conveyor, a picking device movable alonga rail with a trolley, for example, or some other material handlingsystem. The conveyor 118 be arranged between or along each of thestations in the pre-assembly facility 108.

At some point in the pre-assembly process, the particular components ofthe design may be marked, tagged, or otherwise labeled with anidentifier. The identifier may include a sticker, an etching, a printedmark, a QR code, or some other identifier associated with a particularcomponent for identifying the component throughout the process.Accordingly, the pre-assembly facility 108 may include an identificationdevice 116 for providing the identifier. The identification device 116may include a labeler, a laser writer, an etching device, an inkprinting device, or some other system for providing an identifier. Theidentification device 116 may be in communication with the computingdevice and the identifiers may be particularly adapted for associationwith properties for fabricating the component. For example, anidentifier may be associated with dimensional data such as the diameterand length of the pipe and information about one or more bends in thepipe. Other fabrication information may also be associated with theidentifier.

The pre-assembly facility 108 may also include a series of readers 119throughout the facility arranged to read the identifiers and relay theinformation to respective systems for suitably handling the respectivecomponents. For example, the readers 119 may be arranged along theconveyor 118 and, in one embodiment, a reader 119 may be associated witha sorter 120. The reader 119 may be adapted to read the identifier on apassing component and control the sorter 120 such that the component isdirected according to its fabrication properties. For example, thesorter 120 may be configured for directing straight pipes in onedirection and directing pipes needing to be bent in another direction.The associated reader 119 may read the identifier and provide theidentity to the computing device 110, which may, in turn, control thesorter 120 to suitably direct the component through the process. One ormore sorters 120 may be provided throughout the process depending on thecomplexity of the components being fabricated. For example, anadditional sorter 120 may be provided to suitably direct pipes needingto be bent. That is, in some cases, a pipe bend may be performed byequipment and in other cases, a pipe bend may occur manually. The sorter120 at this location may be configured via the sorter module to directpipes capable of being bent by the equipment to the pipe bender anddirecting other pipes to a manual station, for example.

The pre-assembly facility 108 may also include component configurationequipment 122. The component configuration equipment 122 may includedevices configured for forming, shaping, or otherwise configuring thecomponent to fit within the design. In one embodiment, the componentconfiguration equipment 122 may include a bender, cutter, press, orother device for configuring the component as a whole. This device maybe in the form of a CNC machine or other device used to form thecomponent. As with some or all of devices of the system, the componentconfiguration equipment 122 may be in communication with the computingdevice 110 for receiving fabrication instructions.

The pre-assembly facility 108 may also include component finishingequipment 123. The component finishing equipment 123 may include devicesconfigured for finishing the equipment. For example, this may includedrilling holes, performing edge preparations, providing protectivecoatings, threading holes or ends of pipes, or otherwise detailing thecomponent for installation.

Still further, the pre-assembly facility 108 may include sub-assemblyequipment for creating sub-assemblies out of one or more components. Forexample, where a series of pipes are connected together by coupling orelbows or other connectors, the a series of pipes may be connected inthe shop to save time assembling the parts in the field. Thesub-assembly equipment or station may thread a connector onto the end ofa first pipe, for example, and may thread a second pipe onto theconnector, and so on. The sub-assemblies may be provided by sub-assemblyequipment where, for example, a series of components connected togetherremains reasonably handleable and shippable.

The pre-assembly facility 108 may also include a collector 124. Thecollector 124 may be configured for gathering the several components ofthe design as the components come through the pre-assembly facility 108.That is, several of the components of a design may be diverted throughdiffering processes on their way to the collector 124. For example,straight pipes may go more or less directly to the collector 124 afterleaving the selection 114 and identifying 116 stations. In contrast, abent pipe may go through a pipe bending process before being directed tothe collector 124. The collector 124 may read the identifiers on thecomponents coming through the system and gather or group relatedcomponents. The collector 124 may place the several components in a bin,for example. For a particular pipe run, for example, the collector 124may collect all pipe components having related identifiers and thecollector may group and bundle the related pipes for shipping as a unitto the project site. In some embodiments, the collector 124 may affix alabel or other identifier to a bin having components placed thereinwhere the label may provide an indication of what components are in thebin.

The pre-assembly facility 108 may also include a yard 126 for storage ofmaterials waiting to be delivered to the project site. The yard 126 maybe a place where individual components or bins of components are storedprior to shipping to the project site. The yard 126 may include ascanner 128 or other input device for scanning bins or individualcomponents as the bins or components enter and/or leave the yard 126.The scanner 128 may thus be in the form of a reader 119. The scanner 128may be a laser-type reader, an infrared-type reader, an imaging-basedscanner or other device for reading information from a label, stamp, orother identifier. In some embodiments, the scanner 128 may be akin to adigital camera and the identifier on the components or the bin may be inthe nature of a QR code or other two dimensional code. The scanner 128may be used to scan the code and transmit the data to the computingdevice 110. As such, the scanner 128 may include a wired or wirelessconnection to the computing device 110 or to a closer hub for relayingto the computing device 110 such that the materials for a project can betracked. The scanner 128 may include a setting or series of settingsallowing the scanner 128 to be set to reflect a certain stage of theprocess. For example, the scanner 128 may have a switch for setting thescanner 128 to indicate that an item has shipped or has been loaded whenan item is scanned. Other settings may include that the item orcomponent has been loaded into a bin or placed in the yard 126, forexample.

An additional scanner 134 may be provided at the construction site fortracking the components at the site. The scanner 134 may be the same orsimilar to the scanner 128 or the readers 119 used at or near thepre-assembly facility 108. That is, the scanner 134 may be configuredfor reading the labels or identifiers on the components or on the binsand may include one or more settings for indicating the stage of thescanned component or item. As with the scanner 128 at the pre-assemblyfacility 108, the scanner 134 may include settings allowing for anindication of the particular stage of the process the scanned componentis in. The scanner 134, for example, may be set to indicate that acomponent or series of components has been delivered to the job site, isin a lay down area, or is installed in the building, for example. Thescanner 134 at the construction site may be equipped with broad rangewireless communication technology and may be configured for transmittinginformation from the scanner 134 back to the computing device at thepre-assembly facility 108 via wireless communication 140. In otherembodiments, the scanner 134 may equipped with closer range technologyin the form or wired or wireless technology that may transmitinformation to a hub 139 in a job trailer 138, for example, where theinformation may be relayed to the computing device 110 either wirelesslyor via a network 106. In some embodiments, the scanner 134 at the sitemay be interchangeable with the scanner 128 at the pre-assembly facility108. In other embodiments, all of the readers 119 or scanners 128, 134described may be interchangeable with one another.

Turning now to the method 200 of component processing, reference is madeto FIGS. 2 and 3. As shown in FIG. 2, a method (200) of interpreting,fabricating, tracking, and comparing is shown. As shown, the method mayinclude interpreting (202) a model and extracting data from the model todevelop a list, table, or other index of components for use inconstructing a facility. The method may also include several fabricatingsteps including selecting a raw material (204) for fabrication of acomponent and providing an identifier (206) on the component for use inrouting and tracking the component. Other fabricating steps may includeconveying (208) the component through the fabrication facility, sorting(210) between components needing further fabrication and those that maynot, and bending (212) the component to meet the design. Stilladditional fabricating steps may include collecting (214) the componentsand storing (216) the components for delivery. Once fabricated, theseveral components may be delivered (218) to a facility constructionsite, arranged (220) in a lay down or onsite storage area, and laterinstalled (222). At several points throughout the fabrication andinstallation process, the components may be scanned (224) by a reader ora scanner and information regarding the status of the component may becommunicated to a computing device for further analysis or storage.

With respect to interpreting (202), the interpretation process mayinvolve interpreting a design model including one or more systems forsupporting building operations. The design model may be the startingpoint for the process. The model may be a data rich detailedrepresentation design of a facility or product from which data may beextracted, processed, interpreted, identified, tracked, fabricated,delivered, installed, and tallied. This process may not be specific toany given project and may be used at a variety of locations and under avariety of circumstances.

As depicted in FIG. 2, the interpretation software or module may extractdata from the design model. This data may be transformed into a usableidentifiable language to be processed, identity coded, tracked,fabricated, delivered, installed, and tallied throughout this course ofaction. The software may extract the component data, such as pipediameter, for example, the quantity of the components, the material typeand determine whether it should be fabricated (bent, cut, or otherwisemodified) or if it is a unmodified component, such as a straight sectionof pipe, for example. The software or module may designate thecomponents into standard sizes or lengths, such as standard pipelengths, for example.

As shown in FIG. 3, the interpretation software or module may access andextract and input data from the design model database, translating thedata into a usable process form, and storing the data in a separate filedatabase to be used in several processes throughout this operation, Inthe embodiment shown, the interpretation process may extract severalitems of pipe data from the model database. For example, theinterpretation software or module may extract the system type (302), thematerial type (304), and the material size (306). The process may breakdown each pipe run into standard lengths of pipe and extract the bendingangles and number of bends in each section, the distance between thebends in each section while incorporating the pipe gain and the take upfor each bend. The process may formulate and assign an identifiable codefor tracking the alpha numeric code to each pipe length. Theidentifiable code may be scanned and tracked at various stagesthroughout the process. Upon installation and tracked as complete, theinterpretation software database may input the material identified ascompleted data back into the model and compare the data to the overallmodel to obtain a percentage of completion.

In some embodiments, the system type (302) may reflect the type ofservice it is providing. For example, the system type (302) may bedesignated as P for power, L for lighting, D for data, FA for firealarm, SO for sound, SC for security, SY for system, and LV for lowvoltage. Other naming conventions and nomenclatures may also be used andmay be adapted for the particular discipline being supported. That is,for example, in the case of HVAC systems, H may designate heating ducts,while AC may designate air conditioning ducts. In other HVAC cases, Smay designate supply and R may designate return.

The material type (304) may reflect the material the particularcomponents are made of. For example, the material may be designated asGRC for Rigid metal conduit, EMT for Electrical metallic tubing, or IMCfor Intermediate metal conduit. Other naming conventions andnomenclatures may also be used and may be adapted for the particulardiscipline being supported. For example, in the case of HVAC systems,duct work may be designated as G for galvanized ductwork or I forinsulated ductwork or other designations may be used.

The material size (306) may reflect the cross-sectional dimensions ofthe components. For example, in the case of pipes, the pipe size may bedesignated as 0.5 for ½″ diameter pipe, 0.75 for ¾″ diameter pipe, 1 for1″ diameter, 1.25 for 1¼″ diameter, 1.5 for 1½″ diameter, 2 for 2″diameter, 2.5 for 2½″ diameter, 3 for 3″ diameter, 3.5 for 3½″ diameter,4 for 4″ diameter, 5 for 5″ diameter, 6 for 6″ diameter, etc. In otherexamples, such as rectangular HVAC ductwork, for example, the materialsize may be designated as 12×24 or 16×25, for example, indicating thatthe ductwork has a cross-section with a 12″ by 24″ rectangle or a 16″ by25″ rectangle, respectively.

The degree or angle of bend (212) may be between 0 degrees and 90degrees and may be designated as a numeric value with two decimalplaces. For example five degrees may be designated as 5.00, twenty twoand one half degrees may be designated as 22.50, fifty three and threequarter degrees may be designated as 53.75. Other ranges for degree ofbend may be used depending on the application and other degrees ofprecision may also be used.

The length of a given component may be based on standard lengths commonin a given industry. For example, in the electrical conduit industry, alength of pipe may be broken down into multiple standard lengths whenthe pipe length exceeds the standard length and/or listed as itsfinished length if it is less than a standard length when completed. Forexample a one hundred and twenty eight foot run of pipe may be brokendown into twelve ten foot sections and one eight foot section of pipe.(Ten foot pipe lengths are standard pipe lengths in the electricalindustry)

The distance between bends in the pipe run may incorporate formulas tofactor in the pipe gain from each bend and the take up needed for eachbend.

The identifiers later used by the tracking system may be developed asthe interpretation module extracts data from the model. That is, theinterpretation module may break up the several systems in the model andestablish a list of components for each system. The identifiers may bealpha numeric codes that are be applied to each pipe length and they maybe a compilation of the above-described data in an accumulative form.For example, the alpha numeric code may start with a seven digit numberpreceded by the abbreviation produced by the material type designationand succeeded by a dash and a three digit number for each length in therun. The seven digit identifiable code may increase by an additionalfactor for each non connected pipe run. A pipe run may be defined as astring of pipes connected to each other.

In one embodiment, a system of identifiers may be described for twopower pipe runs that are 40 feet long running parallel to two data piperuns that are also 40 foot long. The first component of the first powerpipe may be coded as P-0001001-001, the second component of the firstpower pipe may be coded as P-0001001-002, the third component of thefirst power pipe may be coded as P-0001001-003, and the forth componentof the first power pipe would be coded as P-0001001-004. The firstcomponent of the first data pipe may be coded as D-0001001-001, thesecond component of the first data pipe may be coded as D-0001001-002,the third component of the first data pipe may be coded asD-0001001-003, and the forth component of the first data pipe may becoded as D-0001001-004. The first component of the second power pipe maybe coded as P-0001002-001, the second component of the second power pipemay be coded as P-0001002-002, the third component of the second powerpipe may be coded as P-0001002-003, and the forth component of thesecond power pipe may be coded as P-0001002-004. The first component ofthe second data pipe may be coded as D-0001002-001, the second componentof the second data pipe may be coded as D-0001002-002, the thirdcomponent of the second data pipe may be coded as D-0001002-003, and theforth component of the second data pipe may be coded as D-0001002-004,and so on. Other identifier protocols or nomenclatures may also be used.

Referring to FIG. 4, a more detailed discussion of the operationsperformed by the interpretation module relating to mining data from theBIM model may be provided. As shown, the interpretation module mayreceive input defining the system to be extracted from the model (402).For example, a user may request the data relating to the electricalsystem and more particularly, the power services for the facility. Inother embodiments, the interpretation module may be configured toautomatically mine data relating all of the systems or the systems ofparticular disciplines, such as the electrical systems or the mechanicalsystems, for example. Where the interpretation module is pre-configuredfor mining a particular type of data, the input operation may beomitted.

The interpretation module may access a data file for the selected system(404). The present data file may include coordinate data relating to oneor more assemblies of the selected system. The interpretation module mayread and store the coordinate data from the data file (406).

The interpretation module may also access another data file for theselected system (408). The present data file may include attribute datarelating to the assembly. In some cases, depending on the organizationof the modeling software, the coordinate data file and the attributedata file may be the same file. The interpretation module may read andstore the attribute data from the data file (410) and the interpretationmodule may associate the attribute data with the coordinate data (412).In some cases, the association of the data may occur naturally due toassociations existing in the modeling software.

The interpretation module may analyze the data (414) by breaking up theassembly or assemblies into components based on industry standard orselected sizes. Once broken up, the attribute data may be used todetermine modifications for each of the components. That is, forexample, where an assembly includes a bend, the bend location andradius, for example, may be determined. Other modifications may also beprovided including cutting, hole drilling, welding, and the like. Themodifications may then be associated with suitable components of theassembly. For example, if the assembly included a 90 degree bend 45 feetfrom its start point, then the broken up assembly may include 4 straightpieces of pipe, while the fifth piece of pipe, for example, may have a90 degree bend in it at the 5 foot mark. In addition, provisions forpipe gain and take up may also be provided to assure suitable lengths ofpipe are provided and fit with the intentions of the design model.

The several components of the assembly may be assigned an identifier(416). As described above, this may include assigning a system of alphanumeric labels to each of the components of an assembly. Theinterpretation module may then prepare fabrication instructions for afabrication machine (418). This portion of the operations may includestep by step instructions in machine formatted code for bending a pipeat a particular point and providing a particular radius, for example. Insome embodiments, these instructions may include instructions to feedthe pipe into the machine a particular distance, for example, and thenactuate bending elements or devices to create a bend at a particularpoint along the length of the pipe.

With respect to selecting a raw material (204), as shown in both ofFIGS. 2 and 3, a robotic and/or manual pipe selector 114 may be used.The selector 114 may receive input data from the interpretationsoftware, process the data, and select the appropriate system componentmade of the appropriate material and having the appropriate size to beprocessed. The pipe selector 114 may process this data, and select theappropriate type of material and size of material to be furtherprocessed. That is, based on the material type (i.e., GRC for Rigidmetal conduit, EMT for Electrical metallic tubing, IMC for Intermediatemetal conduit), the selector may travel, move, or otherwise access thean area where the selected material type is stored. The pipe selectormay then select the appropriate pipe size based on the material sizefrom the data provided by the interpretation process. The material sizemay be designated as 0.5 for ½″ pipe, 0.75 for ¾″, 1 for 1″, 1.25 for1¼″, 1.5 for 1½″, 2 for 2″, 2.5 for 2½″, 3 for 3″, 3.5 for 3½″, 4 for4″, 5 for 5″, 6 for 6″, etc. The pipe selector 114 may then deliver theappropriate type and size of material to the identification coding area116, for example, as shown in FIGS. 2 and 3.

With respect providing an identifier (206), as shown in both of FIGS. 2and 3, each component may be identified with a code. Providing anidentifier may include laser etching, affixing a label, or otherwiseassociating an identifier with a component of the system. Theidentifiers used for association may be input from the interpretationmodule. The identifying equipment 116 may code each piece of materialwith a unique identification code that will be used throughout thisprocess, product tracking, product installation and verification ofmaterial completion. As discussed above, the equipment 116 that is usedto perform this process could be a bar coding machine, a laser engravingmachine, or a labeling machine. Other equipment 116 may also beprovided.

With respect to the conveying operation (208), as shown in both of FIGS.2 and 3 and also is depicted in FIG. 1, the conveyor system 118 maytransport the material from the identification coding stage 116 to thebending stage 122 or to the transportation stage 124 either manuallyand/or mechanically based on the input from the interpretation softwareand identification code. Pipe lengths designated as straight may beconveyed directly to the transportation bin 124, while pipe lengthswhose identifiers are associated with attributes such as a bend orseries of bends will be diverted to the bender process.

With respect to the sorting operation (210), a gate or other device fordiverting the flow of components may be used to suitably direct thecomponents. In some embodiments, for example, the sorting operation mayinclude scanning the component with a reader 119 and communicating thecomponent identifier to the computing device 110 and awaiting aresponse. The computing device 110 may receive the communication fromthe reader 119 or scanner and review the details of the part that wasscanned. Where the part requires further fabrication, the sorter 120 maydirect the component for further fabrication. Where the part does notrequire further fabrication, the sorter may direct the component to thecollection area for collection by the collector 124. In still otherembodiments, rather than scanning the component and communicating it tothe computing device 110 for analysis, the reader 119 may have a storagemedium and a processor for determining the direction of a component. Instill other embodiments, the system may be programmed ahead of time andsequenced to fabricate components on an ongoing basis. In thisembodiment, the sorter 120 may, instead, direct the component based onits order in a stream of components. It is noted that while the sortingoperation (210) has been described as relating to whether a componentneeds to be bent or not and relating to only one decision throughout theprocess, those of skill in the art will understand and appreciate thatseveral sorters 120 may be used to control the flow of components to oneor a plurality of further or alternative fabrication devices. That is,for example, in addition to bending or in lieu of bending, a rawmaterial may be cut to length and a sorter 120 may be used to directparticular components to a cutter.

With respect to bending (212), a component may be fed into a componentconfiguration device 122 and formed. As shown in FIG. 5, the method mayinclude receiving or accessing data relating to the size of thecomponent, the radius of the bend, and the location of the bend orbends. The device may then adjust any dies, rollers, breaks or otherfeatures to accommodate the component. The device 122 may then receivethe component from the conveyor 118 or other feeding apparatus and mayroll, break, or otherwise bend the component. In some embodiments, thedata may be input into a CNC machine for example, and the component maybe bent according to the instructions and dimensions provided to themachine. In some embodiments, a manual bender may be used. The equipment122 will execute bends based on the input and/or information from theinterpretation software. This can be either a single pipe bend and/ormultiple pipe bends in each length of pipe. Following the bending stage122 the pipe may be transported to the transport bin 124 and tracked atthat point by the identification code. Other processes may also beperformed on the way to the transport bin 124.

With respect to collecting (214), the components may be directed fromthe one or more devices used to form or finish the components to acollector or bin 124. The collecting may thus include conveying thecomponents to a collection area and placing the components in acollection device or bin 124. The collecting operation (214) may alsoinclude providing an identifier on the collection device or bin in whichthe fabricated components are placed. The collection (214) of thecomponents may include grouping several related components together. Forexample, in the case of electrical conduit, a particular run of pipe mayinclude several components and each of the components in the run may becollected and placed in a common bin. Other grouping approaches may beused and multiple bins may be used where a particular group does not fitwithin the bin, for example.

The transportation bin 124 may be loaded with material and anidentification code for product tracking in the same manner previouslydescribed in the material identification coding section may be providedon the bin. As before, the code may include a barcode, a laserengraving, a label or other identifying device or system.

With respect to storing (216) the components, a yard 126 or internalstorage area may be used until a project site is ready to receivecomponents or until a sufficient number of bins 124 are populated forefficient shipping to the project site. The bin 124 may be placed in orconveyed to a storing area (216) and the bin may be scanned (224) or thecomponents in a bin may be scanned (224) as being stored there. Thescanner 128 may transmit this information to the computing device 110 toupdate the status of the respective components as fabricated and stored,for example.

With respect to delivery (218), loaded bins 124 may be tracked by theiridentification code and loaded onto the delivery truck and delivered tothe installation site 142. The bins 124 or components in the bins 124may be scanned (224) as they are loaded onto a truck, for example, andthe scanner 128 may communicate with a computing device 110 to updatethe component status as shipped.

Upon arriving at the project site 142, the bin 124 may be unloaded,scanned (224) by a site scanner 134 and signed for. The scanner 134 maycommunicate with the computing device 110 via local network connectionor a WiFi, cellular, or other wireless connection 140. The bin 124 maybe transported to an installation area (220) and further scanned (224)and signed for by the foreman where the components in the bin 124 may beunloaded. The scanner 134 may communicate to the computing device 110that the components of a bin 124 are in a lay down area 132, forexample, awaiting installation. The bin 124 may then be sent back to thepre-assembly facility 108 to be re-assigned and reused. The componentsmay then be installed (222) and scanned (224) once installed. Thescanner 134 may then communicate back to the computing device 110 thatthe scanned components are installed.

Regarding the model comparison (226), the model may be updated with theinformation regarding the material designated as installed from theinterpretation and tracking software as either complete or incomplete.The completed items may be compared and calculated with the overallquantity of items in the model to provide an accurate percentage ofcompletion of the total project model.

That is, upon installation of the material and it being registered ascomplete, the interpretation software database may input the materialidentified as completed data back into the model and compare theinstalled portions of the model to the overall model to obtain apercentage of completion. The model comparison may be a continualprocess throughout the duration of the project until the completionpercentage reaches one hundred percent complete.
